IMPROVEMENT IN VENTILATORS FOR BUILDINGS.-

Specification forming part of Lettersl Patent No. 128,502, dated July 2,1872.

Specication describing a new and useful Improvement inVentilatin gBuildings, invented .by JOHN ONEIL, of New York city, in the county andState of New York.

In the accompanying drawing, Figure 1 is a detail vertical section of abuilding to which my improved ventilators have been applied takenthrough a plane 'parallel' with a partition-wall. Fig. 2 is a detailvertical section taken through the line y y, Fig. 1. Fig. 3 is a detailcross-section of the same taken through the line m ar, Fig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the ventilation of houses andother buildings having inner or partition walls, so that the foul orvitiated air may be carried ofi' and discharged into the open air, andat the same time in such a way as to take up no extra space and causebut little extra expense; and

it consists in the inode of Ventilating through the partitions,as-hereinafter more fully described.

This mode of ventilation is applicable to all buildings which have inneror partition walls extending vertically from the lower iioors to theroof or garret. These inner or partition walls are constructed in theordinary manner by attaching laths and plastering or boards to theopposite sides of studs, thus forming as many vertical dues or spaces Aas there are studs, less one. I use not less than three of these fluesin each apartment to be ventilated, forming an opening, B, intoeach-into one through the base-board, into another at a point about fivefeet above the floor, and into the third at or near the ceiling of theroom, as shown in Figs. l and 2 of the drawing. These openings should beprovided with ordinary registers, I have found a great advantage inpractice in the use in the same room of openings at diiierent heightsconnecting with inde pendent ilues.

Care should be taken that no two openings, B, either upon the samey sideor upon the opposite side of the partition-Wall, or upon the same dooror upon dierent lioors, lead into.

the same iiue or duct A. Where beams are encountered the ducts must bemade continuous by forming holes through them.

At the garret all the ducts or iiues A of the same partition or of thesame part of the building may be led into a common duct passing outthrough and rising to a suitable height above the root' of the building'. This common duct or flue may be made of boards or other suitablematerial, and its upper end should be provided with a cap or cover madeof galvanized iron or other suitable material, and so con structed as toprevent the entrance of rain o r wind, while allowing the foul air tovescape freely.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The mode of ventilation herein shown anddescribed-that is to say, by using the spaces between the studs andlaths as air-ducts, three,

at least, of said ducts being used for each apartment, so that there maybe three openings leading from the apartment into vsaid ducts-one intoeach, one being placed near the floor, one near the ceiling, and a thirdat an intermediate point' about live feet from the floor, and the wholeconnected with a proper chimney or exit-due at the top of the house andwith suitable ingress-passages for fresh air, in the manner and for thepurpose shown and described.
